Wrap the piping joints with thermal insulating materials and then wrap with a vinyl tape.
Thermal insulation
Thermal Insulation piping:
a. Place the drain hose under the piping.
b. Insulation material: polythene foam over 6mm in
thickness.
NOTE: Drain hose is prepared by user.
• Drain hose should point downward for easy
drain flow. Do not twist the drain pipe, leave it
sticking out or waving around, do not immerse
the end in water. If an extension drain hose is
connected to the drain pipe, make sure to be
thermally insulated when passing it through the
indoor unit.
• When the piping is directed to the right, piping,
power cable and drain hose should be thermally
insulated and fixed at the rear of the unit.
Piping Connection:
a. Connect indoor unit pipes with two wrenches.
Pay special attention to the torque allowed as
shown below to prevent the pipes, connectors
and flare nuts from being deformed and
damaged.
b. At first fingers-tighten them, then use the
wrenches.
